Repeated Citations in Footnotes - Short Form


I would like to edit the style of the short form in Endnote (X2). For example, I’d like a repeated citation (that is cited fully when appearing for the first time) to appear in my footnotes as

Arago 1839, p. 20.

I know a workaround could be to enter the year in the “Short title” field, but that still leaves me with formatting problems (the short title is formatted in the same way as the title, producing e.g. italics).

Is there any way to edit the short form?

Thanks for your ideas,
